[Problems to be solved by the device]

 By the way, if a battery holder installed in an electric device is connected to the battery compartment in the wrong direction, the dry battery is installed in the reverse direction, or if it is not, the battery itself is defective or aged. It has been reported that there is a risk that the dry battery may be damaged in the holder and liquid leakage may occur due to aging. If the battery leaks in the holder, it is limited to local contamination as long as it stays in the holder, and there is little concern that it will cause significant damage to the left, but the most serious case. As an example, the leaked electrolyte may flow into the body as it is and drip, which may attack the central electronic components inside the body and cause irreparable damage to the entire equipment.

However, in the case of a battery holder of a type having an opening for conducting a lead wire on the side wall of the battery housing described above, when the dry battery leaks in the holder, the leaked electrolysis occurs. It has been pointed out that the liquid may easily flow and drip into the main body through the opening on the side wall of the battery housing from the bottom surface of the holder, and the above worst case cannot be avoided. Is recognized.

The present invention pays attention to such a technical problem, and particularly in a battery holder of a type in which a side wall of the battery housing is provided with an opening opened from the bottom surface of the holder, the dry battery leaks in the holder. It proposes appropriate measures to prevent electrolyte infiltration into the main body in the case of occurrence of electric shock.

[Means for Solving the Problems]

 In the battery holder according to the present invention, as a means for achieving the above object, an opening is formed on the side wall of the battery housing section from the bottom surface of the holder, and the bottom surface of the holder is provided near the side wall of the battery storage section. A weir portion that projects further is provided.

[0007]

[Action]

 In the case where such a weir is installed, the weir is opened on the side wall of the battery housing from the holder bottom even if the housing dry battery leaks and the electrolyte leaks to the bottom of the holder. It blocks the inflow of electrolyte into the device and prevents the inflow and drip of the electrolyte from the opening.
